    I don't think i would want to go at it with sand paper like the link but wouldn't a bit of metal polish go a long way?

    To gain what? something thats polished that does nothing then you have to cover it up?

    Don't waste your time with it

    I think its meant to give better flow, A bit like when people smooth out the air box.

    No gain at all

    Don't bother wasting your time and money

    This is advise from some that has spent years porting cylinder heads, There is flow bench tests out that that prove its all a waste of time.

    Any polishing of the inlet side of the engine isn't worth it. It can in fact, make things worse.

    Yes, the "making it worse" part but it's still a waste to polish the inlet side. What's more important is nothing effecting overall flow, like steps as I'm sure you know.

    You efforts are better spent polishing the paintwork ;)
